To all whom it may concern:

Be it known that l, EDWARD (l. F oiuo,

a ci izen of the United States, residing at Hohoiten, in the county of Hudson and State of New Jersey, have invented certain new and useful improvements in Car-Heatin Apparatus, of which the following is a in 1, clear, and exact description, such as will enable others skillecl in the art to which it a pertains to make and use the same.

T1 is invention relates to car heating apparatus. 1

One of the ohjects thereof is to provide simple, practical and 'efiicient heating epparatus for 'cers. t

Another obgect is to provicle in apparatus of the ebov'e nature thermostatieslly-controlled valve mechanism of i ipie' and clureble construction adapted to not freely and etliciently under all conditions of use.

Another object is to provide a paratus' of the type first mentionecl in whic expansion of a portion of the heating apparatus is utilizeti Without tendency to strain any of the ports.

Other objects tireto-provitie in apparatus of the above general nature, positive anti reliable scljusting means and convenient means for nienuel control of the parts.

so, Other objects will be in port. obvious emi in art pointed out hereinafter.

he invention accordingly consists in the features of construction, combinations of elements and arrangement of parts which will be exemplified in the construction herei'ncttei set forth, and the scope of the epplicotion which will he inclicotetl in the following claims.

In the accompanying drawing, wherein is shown one of various possible embodiments of this inveiltion, Figure l is a the; graminatic perspective View thereof. Fig. 2 is e side elevation, partially in section and showing adjusting; and controlling means. Fig. 3 is a side elevation of automatic controlling means. is a sectional view along the line of of Fig. 3, showing the parts on an enlarged scale. Fig. 5 is a sectional view taken along the litie y-y of Fig.

Similar reference characters refer to simi lar certs throiwhout the several views of the drawings.

Refer-sin now to Fi 1 01" the rlrawin 's 1 e v s b i there is snown mounteti benestn s cm: floor pipe 2, from which steam connections 3 lead to each sideoi" the car. As the apparatus upon hot-h sides of the car is substantially;

identical that upon one side only will be de'scribefi in detail. Steam pipe 3 leads to compartment 4 in e. fitting or casing 5.,

Tapped Within this casing upon an ennular shoulder 8 is a. collar '2' having therein a gasket '8, forming s seat for the valve 9, actuated as hereinafter described. From the compartment 10 of'cosin 5 upon the remote side of the collar 7 lezfisa steam pipe 11 throu h suitable elbows to afittine' 12. D 1 L: oest shown 111 Fig; i of toe drawings.

Within this fitting is cast an injector member 13 hsvmg teppecl therein the nozzle 14.-

I and guide collars 15 anti 16. The steam entering from pipe 11 passes within the annuler space 17 between. collars 15 and 16 encl its passage toward the nozzle 14 is controlled by a piston valve 18, which is controlled in turn as hereinafter described. From the injector fitting 12 the steam is ieti through radiating pipe 19 toward and pertially across one end of the'car, thence turnmg downwardly and returning to the opp site end of the car through the concluit i.

Midway in this conduit is positioned a drip pipe 21 which is preferably openeglto the atmosphere, a though, it'clesired, a trtip may be utilized, todrain ofi the water of condensation. From conduit the steam passes upwardly and thence returns upon itsel: in conduit 22, also forming a part oi the raclieting pipes. Thislast mentioned pipe 22 is held in fixed position as by s.

clamp 23 at a predetermined point. spaced from the injector fitting 12, above described. Conduit 22 terminates at its free end Within a collar tapped Within a fitting 24 having three-tied into its remote end a colic): 25 hearing short pi e 26, which forms a Vlb tucl extens on of t to pipe This last pipe passes through a. suitable shitting-box 2 mounted upon the fitting 12 and discharges the ste n otter itspassage through the radiator intothe choices 28, from which it is sucked by the jet of live steam at the nozzle is to again circulate Within the sys- The spindle 2-9 of the valve 18 is threetlecl vvithin a. sleeve ancl its squs-recl shank 31 tlence passes through the guiele .32. Sleeve 36 is rotatable bet-ween a pair e? supports 33 end is'proviclecl with suitwidely difierent embodiments of this invention could be made without departing from the scope thereof, it is intended that all matter contained in the above description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense. It is also to be understood that the language used in the following claims is intended to cover all of the generic and specific features of the invention herein described and all statements of the scope of the invention, which, as a matter of langua 'e, might be said to fall therehetween.
